Doomed Exynos 2300 SoC shows up on Geekbench's ML benchmark database
At this point, it is abundantly clear that the Exynos 2300 is dead and buried, although we may get to see it in spirit alongside the Pixel 8 series' Tensor G3. However, there are a few pre-production samples of the chip out there, which have now been tested on Geekbench's ML benchmark (H/T @QaM_Section31), where it scored a paltry 456 points. It appears that someone has been tinkering with it for a while, as the earliest listing dates back to nine days ago (May 18).
The Exynos 2300 was spotted alongside a device titled Samsung SM-S919O, which doesn't match the description of any off-the-shelf Samsung phone, effectively confirming its presence in a prototype device. However, the listing sheds some light on the CPU's core configuration and clocks. Unlike its predecessor (and most mainstream SoCs), the Exynos 2300 packs a total of nine cores in three clusters. Its prime core is clocked at 2.6 GHz, four more (likely) performance cores at 2.59 GHz and four efficiency cores at 1.82 GHz.
This tells us that Samsung has no qualms about experimenting with odd core counts, reinforcing rumours about the Exynos 2400 launching as a 10-core SKU. However, it is said to opt for a 1+2+3+4 CPU core split, which, in essence, isn't all that different from that of the Exynos 2300. Besides, even the Qualcomm Snapdragon 8 Gen 3 could launch with quad-cluster CPUs if recent rumours are accurate.
